Follow the instructions: the upper and lower layers are filled with boiling water above 98 degrees(Keep above 42 degrees for 10 hours)of,
The product is mass-produced, automated flow operation, the products are the same, and the insulation is the same under the same conditions.
Heat preservation of food: This has a lot to do with the temperature of the food after everyone puts it in the jar. The length of the heat preservation time for the food depends on whether the temperature of the food in the can is high enough or not, and the temperature is high enough, there is no problem in keeping the heat for 6-8 hours, otherwise the time is short.
The length of time the food is ready to be placed, the speed of loading the food, and the temperature of the food can affect the length of the holding time, which has a great relationship! The higher the temperature and the higher the quantity in the tank, the longer the holding time, otherwise the shorter the holding time. The heat preservation tank is not a constant temperature tank. The heat preservation tank achieves heat preservation by slowing down the temperature loss of the food. If the temperature of the food is not high enough at the beginning, the heat preservation time cannot be long!
This is a vacuum insulation tank, and the insulation is very good
